What is local
The words you use, in the numbers you use.
Grownz does not translate finance into jargon. It uses your currency, your number format and the words your bank already uses.
Mortgage
A home loan. Grownz shows the interest and principal split of each payment and what an overpayment saves.
Overpayment
What the Prepayment Lab models: a lump sum against the balance and the months it removes.
Pension
Held under the retirement asset class. Growth is not passive income until it pays out.
When paid plans open, Plus and Pro will be billed in US dollars through Stripe; your numbers stay in pounds. Grownz never sees your card details. Today every household starts on Free.
